Streszczenie
We give (necessary and sufficient) conditions on a sequence of functions under which every generalized Stieltjes moment problem \int_{0}^{\infty} f_{n}(x)\phi(x)\,{d} x=a_{n}, \ \quad n\in\mathbb{N}, has solutions \phi\in\mathcal{S}(\mathbb{R}) with \operatorname{supp} \phi\subseteq[0,\infty). Furthermore, we consider more general problems of this kind for measure or distribution sequences \{ f_{n}\} _{n=0}^{\infty}. We also study vector moment problems with values in Fréchet spaces and multidimensional moment problems.
